Windows 7 Profesional has no problems in itself with Calibre, but acording to Kovid the WMI susbsytem (or some of its' files) can become corupt. Acording to "WMI Control" in Administrative Tools, WMI is working correctly. But not according to Calibre.
With Calibre having trouble with WMI on 2 of my computers it will not find the PRS-600.
I have searched the net and the Microsoft Knowledge Base. None of the solutions have helped. Kovid sugested that the only way he knows to fix it is to re-install Windows. My Win 7 system is going on 3 months and I just don't feel like doing that.

Bummer, I had a sense the problem was something along these lines. It can be frustrating I know and I agree that I would not want to do a re-install. Have you considered a "repair install"? I am not even sure if Win7 has a repair install option anymore. I get the sense this issue is certainly not isolated to your system nor Calibre...it means there will hopefully be a patch in a patch or service pack, though I imagine a service pack update is months out yet though I am sure it is already in the works...probably began during the late beta when most stuff is already locked in and won't be addressed right away unless it's really serious.
For now can you manage things OK with just Windows Explorer or whatever Win7 calls it now?
I don't recall if you tried running a Win XP VM to see if it works, but because the VM still must go through Win7 it will end up bumping into the same issue...in theory anyway.
Sorry the news was not better. I wonder how many other people are affected with this WMI problem and is it isolated to only Sony devices, but from Kovid's explanation, other software or drive that depends on WMI will hit the same wall...this is up to MS to address I suppose. But I would look into the non-destructive repair install, that could do the trick unless of course MS decided it's not needed anymore...sigh...some days!!
